  1. Homeostasis (definition)
    Temperature
  2. Endotherm
    organism generates heat within
  3. Ectotherm
    Organisms get heat from external sources
  4. Types of Homeostasis
    • Metabolic Production: as metabolism increases-heat increases
    • Insulation: fur,feathers,blubber,fat layers
    • Evaporative clothing: warm weather (sweat, pant, saliva)
    • Behavioral: migration (birds)
    • circulatory: dilate or constrict blood vessels
  5. Homeostasis-water balance-kidneys
    • A. Filteration: H20 and small molecules forced through capillary walls
    • B. Reabsorption: Water, sugars, salts retun to blood
    • C. Secretion: Substances forced back to urine track
    • D. Excretion: Urine products passed to bladder
  6. Solute-ADH-Water reabsorption
    • Increased Solute:--ADH increases in blood- water reabsorption increases
    • Decreased Solute:--ADH decreases in blood- water reabsorption decreases
